Abstract
Circuits and techniques are described for compensating for a first parasitic current corresponding to a first parasitic capacitance associated with a first switch. A second switch is configured substantially the same as the first switch, the second switch having a second parasitic capacitance associated therewith. A current mirror coupled to the second switch generates a compensating current in response to a second parasitic current corresponding to the second parasitic capacitance. The compensating current compensates for at least a portion of the first parasitic current.
